Promach 3D has installed its second Sodick wire-erosion machine from Sodi-Tech EDM to boost capacity and keep up with customer demand. The new Sodick ALC 400G has been set to work producing fir-tree profiles on special tooling for a critical aerospace application.
Established in 2004 by Matt Fazekas, Promach 3D has grown into a 12-employee business turning over in excess of £1 million per annum. The company has created a strong niche by focusing on bespoke projects for high-end markets, the principal one being aerospace. Typically, the parts, tooling and assemblies manufactured by Promach 3D are complex in design, with high tolerance and surface finish demands.
“We recently introduced an additional facility in Derby, and decided to invest in a second wire EDM, not just to increase capacity, but to take advantage of the latest technology,” explains Mr Fazekas. “Although we looked at the whole market, due to the reliability and functionality of our AG600L, we returned to Sodi-Tech EDM. The ALC 400G was the right machine for our requirements, largely thanks to its versatility and high specification. As a subcontract business, we never know what will come through the door tomorrow, so we have to be prepared and continue to offer high-end solutions.”
“We won an aerospace contract that in the first instance involved liasing with the customer to assist with the design-for-manufacture of stainless steel tooling that helps automate the coating of turbine blades. From the outset it was clear that, due to the complexity of a key feature, wire EDM was the only way it could be made effectively and efficienty.”
“We designed a fixture to EDM 20 root holders at a time on our new Sodick, typically running lights-out over a 12-hour cycle time.The Automatic Wire Threading technology is excellent, which means we can leave it to run assured of its reliability. If we need to run the machine over a longer unattended period, we can use the Sodick Jumbo wire feeder for a full weekend’s worth. To be honest, once set up and programmed, the machine just looks after itself, working quietly in the background. Also worth a mention is that the cutting speed of our new Sodick is faster than our six-year-old wire EDM, probably by at least 10%.”
